iOS 6中UILabel具有多个字体大小的NSAttributedString行之间的相等间距

我试图在每条线之间获得完全相同的垂直空间
但是,显示的内容具有可变空间。就好像有什么东西在根据字体大小为字体添加垂直边距

为了使代码在每行文本之间不显示任何空格,我应该使用哪些代码?我一直在做类似的事情,所以您可以尝试类似的方法(在浏览器中键入,小心!):
NSMutableParagraphStyle*style=[[nsmutableparaphstyle alloc]init];
[style setAlignment:NSTextAlignmentRight];
[样式设置行距:0];
用于(NSString*行中的行RAY){
NSMutableParagraphStyle*subStyle=[style mutableCopy];
[subStyle setMaximumLineHeight:10];//使用此值玩游戏我一直在做类似的操作,所以您可以尝试类似的操作(在浏览器中键入,小心!)
NSMutableParagraphStyle*style=[[nsmutableparaphstyle alloc]init];
[style setAlignment:NSTextAlignmentRight];
[样式设置行距:0];
用于(NSString*行中的行RAY){
NSMutableParagraphStyle*subStyle=[style mutableCopy];
[subStyle setMaximumLineHeight:10];//在属性字典中使用此值,将“paragraphStyle”更改为“style”对我来说很有效。我有一个稍微不同的情况,即在长字符串中的句子上需要段落间距,而不是在数组中,因此不需要for循环。在属性字典中,更改“paragraphStyle”“风格”对我来说很有效。我有一个稍微不同的情况,在一个长字符串中的句子上需要段落间距,而不是在一个数组中,所以不需要for循环。
